How To Cut Back On Deceased Sunflowers?

This guide provides a step-by-step guide to pruning sunflowers. It starts by assessing the plant closely and identifying any dead or damaged leaves, flowers, or stems that need to be removed. Then, using pruning shears, carefully remove any dead or damaged parts. Thin out crowded areas, control height (optional), and deadhead the plant.

Perennial sunflowers need trimming in early spring to remove dead or weak branches. In late spring, you can shape the plants. During late summer, cut back the plants. Deadheading sunflowers involves removing fading blooms before they have a chance to produce seeds. Deadheading sunflowers is usually done in the fall, but perennial sunflowers are usually smaller and multi-headed. Deadheading sunflower blooms is fairly simple: look down the stem from a bloom you want to remove and locate the first set of leaves. If the sunflower is a multistem variety, look down a faded one. A good rule of thumb is to prune them back to half their size in late spring or early summer, then cut them back by about a third in June or July. If you want to harvest the seeds, leave the dead heads until the green bits behind the flower turn brown.

Sanitize your tools with rubbing alcohol and get the timing right – lop off flowers when they look tired and prune your common sunflowers in early to mid-spring to set the stage for a spectacular show. For perennials, consider a mid-summer trim to combat legginess.

After removing the dead heads, lay the sunflower head flat on a clean surface or place it in a container to trim it into the desired shape.
